Catecholamines, which include neurotransmitters like dopamine, norepinephrine, and epinephrine, play crucial roles in the body's response to stress and regulation of various physiological functions. They are involved in the "fight or flight" response, increasing heart rate, blood pressure, and energy availability. Additionally, catecholamines influence mood, attention, and arousal, impacting both physical and psychological responses. They also help regulate metabolism by promoting glucose release and fat breakdown.
catecholamine
yes it is
no serotonin is not a catecholamine. Catecholamines are dopamine, epinepherine and norepinepherine.

Dopamine, norepinephrine, and epinephrine are catecholamines.
When a catecholamine or peptide hormone binds to receptors on the surface of a cell, it triggers a signaling cascade inside the cell that leads to various cellular responses. This can include changes in gene expression, activation of enzymes, alterations in cell metabolism, and modulation of cellular functions. Ultimately, these responses help the cell adapt to its environment and maintain homeostasis.

Examples of neurotransmitters that are not catecholamines include serotonin, glutamate, and GABA (gamma-aminobutyric acid). These neurotransmitters play essential roles in various functions within the brain and nervous system, such as regulating mood, cognition, and motor control.

The catecholamines test can be performed on either blood or urine.
